IMPROVEMENT IN SELF-OILING BOLSTRS.

Specification forming part of Letters Patent No. 146,418, dated January13, 1874; application filed November 8, 1873.

To all whom it may concern:

Be it known that 1, J OIIN D. WELLS, Jr., of Putnam, in the county ofWindham and State of Connecticut, have invented a new and ImprovedBolster and Spindle Lubricator, of Vwhich the following is aspecication:

My invention consists of an oil-chamber in the hub of the gear, Whichruns on they bolster and revolves the bobbin, with a small passage fromthe bottom of it to the hole through the wheel forthe bolster; also, aslot in the latter to the spindle, by which the oilsupply is carriedfrom said chamber and delivered to the bolster only While runnin g, andfrom the bolster the oil finds its way through the slot to the spindle,in a manner calculated tolubricate the parts eliiciently, and at thesame time economize the oil. The oil-passage from the Oilchamber to thebolster-hole of the gear prevents the Waste of oil VWhile the niachineis not running, in consequence of being so small that the Oil can onlyioW when the part-s are in motion, and there is a little draft which iscaused by the motions.

Figure l is partly a side elevation of my in vention, and partly asectional elevation. Fig. 2 is a horizontal section on the line w x,Fig. 1, Fig. 3 is a top view of the bolster and gear.

A is the gear for turning the bobbin. B is the bolster on which the gearA runs, and in `which the spindle runs. C is the Oil-chamber in the hubof the Wheel; D, the oil-passage from the chamber to the hole in thegear, for the bolster. E represents slot-s in the bolster, to admit oilto the spindle,Which Works in the tubular space within it. F representsa hole for filling the oil-chamber; and G, an air or The arrangement iseqiially"`applicable to Speeders, English frames, iiy-frames, androving-frames.

Having thus described my invention, I claim as new and desire to secureby Letters Pat'- ent A gear-Wheel having hub A, with oil-.chamber C andchannel-ways D F, in combination With shaft B having slots E,substantially as and for the purpose described.
